JTAG MK II and /RESET
2005-04-13 by alwelch93021
Having my JTAG work for hours and then refuse to go into debug I looked over all the signals and only thing I found suspect was the /reset line. Data sheet shows it should pull up to .85 X VCC and I run +5 VCC. My reset was showing a high level of around 3.2vdc with a 10k pull up on the line. I plan to reduce that to 5k today and see what i get. Any one else seen problems with JTAG refusing to start debugging when the /reset was not pulled up enough? Al Welch
